5 Arrangement of the international cooperation The bilateral agreements The exchange of all information related to flood protection and actual flood routing is realised by the Directivies for the forecasting, reporting and warning duty on the Czech-Slovak border waters and Czech-Austrian border waters River basin rivers The Danube river basin Morava The Danube river Basin Dyje, Morava Riparian countries Czech Republic Slovakia Czech Republic Austria Treaties Treaty between the Government of the Czech Republic and the Government of the Slovak Republic about cooperation on transboundary watercourses Treaty between Czechoslovak Socialist Republic and the Austrian Republic on regulation of water management issues related to border waters Year of establishment

8 Conclusions The flood damages were estimated on 35 mil. Eur, there were large damages on the agricultural land due to flooding Three people lost their lives during the flood Lessons learned 60 % of the Dyje catchment lies in Austria, cooperation with Austrian institutions must be improved The permanent task is improving of the meteorological and hydrological forecasting and warning

20 Central European Flood Risk Assessment and Management CEFRAME Goal of the Project In the CENTROPE Territory (Morava, west Slovakia, Northwesthungary and Austria) there are the rivers Morava-Dyje, Danube and Leitha For this territory we must - compare and analyse the existing Floodprotection directories - flood risk analysis - harmonization of the flood design criterias

rivers Morava-Dyje, Danube and Leitha For this territory we must - compare and analyse the

21 CEFRAME - results Review and assessment of the current situation (including natural, hydrological conditions, floodplains and flood defences) Flood risk analysis and mapping Potential Damage Maps Draft for the harmonization design criteria and safety regulations along and across border sections, Floodmanagement To raise the awareness and preparedness of the general public Example for the other regions (Best Practice)

22 Area for cooperation improvement to interlink regional and national agencies on sub-busins to facilitate and promote the exchange of source data Routing of the information downstream as the basis of improving efficiency and lead time of flood forecasting and warning To improve the methodology and tools of data collection, processing, forecasting and dissemination Harmonization for a common approach in assessment of flood-prone areas and evaluation of flood risk (CEFRAME)
